Sorry for the long post in advanced. Newbie here. I'm attempting to plan a split phase 50amp rv build. The rv runs off mostly 12vdc with 50a split phase shore power. I plan on using 2 victron inverters and equipment to power new system. The question I have is running it on 12v or 24v or 48v (can you run 2 inverters on 12v)? As of right now my 12v loads are constant 50 to 60 amps with a need for a surge to about 150a when running the jacks and slides, for only a few minutes. On the ac side I would like to be able to run 2 13k airconditioners and various other things. The problem I'm having is if I use the higher voltages I have to convert back to 12v at 160amps or have a separate 12v battery with separate charging of about 70amps to cover my loads which adds complexity, inefficiency and money. I understand cable sizing for using higher voltage but converting back and forth voltage is also a problem. Also which inverters should I use multiplus2 2x120 3000va or a multiplu 2 5000va if using 48v? Thankyou for your input.
